Change Base URL in Magento cannot change back, SQL edit

Try to change my Magento store URL today, at first I thought it works, but after that found out that it goes missing, not so much as missing content, more to having a page without any CSS design at all. Some people said they got '404' error popping up.

It left me panic stricken for a while, but after that did the following;

1. Go to MyPHPadmin and my magento store database and locate the following 'core_config_data' just like this video

2. Change the secure BASE_URL and BASE_URL here to your desired base url
3. Go back to your Cpanel (or other web hosting manager you have) login via FTP can also do the trick,go to your magento folder and clear all the file in var/cache and var/session also temp. Clear your computer cache too, sometimes your browser is a bit slow in re-caching.
4. This should work, if not try login-in into your Magento admin panel via the design-less page, find the index management and clear your index there.

Hopefully this work for other people facing the same problem as me.
